IMPROVEMENT IN TOPICAL HEATERS FOR OIL-WELLS.

Specification forming part of Letters Patent No. 118,384, dated August 22, 1871.

To all whom 'it may concern:

Be it known that I, ELizUR NEWBERRY, of Titusville, Crawford county, State of Pennsylvania, have invented an Improved Apparatus for` with exactness the crevices in artesian wells sunk for the purpose of obtaining oil; and second, to cleanse and open those orevices by boiling and dissolving the p aiane and other impurities with which they are generally clogged.

For this purpose the round bar A, of copper, brass, iron, or other metal, of diameter and length suitable to the size of the hole, is laid upon the iron forks B B driven into the ground, and heated over a lire toas great a heat as can be obtained short of the melting-point. It is then lowered into the Well by the graduated chain C, measured off so as to allow of its suspension directly opposite to the oil-bearing crevices.

The intense heat of the bar Will cause the Water to boil in the Well and crevices adjoining and melt and clear out the paraftine and other substances clogging them. Every fth link of the chain, making one foot in length, is designated by a tie or cross-bar; every ten feet in length of the chain is pl'aced alink marked X, Xx, Ste.; and every one hundred feet a link marked c, cc, &c.

The inelasticity of the chain and the liueavy Weight of the bar at the end Will obviate all the difficulty here experienced in making a correct measurement ofthe depth of a Wella fact upon which depends all the efticacy of any methods employed to clear the crevices.

I claim- The heated har A, in Vcombination with the grad-
